DIRECTIONS FOR USE

Preliminary Statement:

Prior to application it is necessary to read the Material

Safety Data Sheet for information about precautionary

measures and safety recommendations. Also, for chemical

products exempt from compulsory labeling, the relevant

precautions should always be observed.

Preparation:

The surfaces of the substrate must be dry and free from oil,

grease and dust.

Application:

Application Temperature : 225 to 240 ℃

Application System : Hotmelt application systems

When bonding to a substrate with high thermal conductivity

the use of a specific application temperature is required for

good wetting

Do not heat the product above the specified application

temperature range.

When the product is not in use do not apply heat, this will

degrade the quality of the product and in extreme cases

cause carbonisation. The standby temperature for the

product is approximately 50°C below the application

temperature, but not for longer than 72 hours.

MACROMELT 6812 may absorb moisture from the air. This

will not be apparent in the solid form, but may cause

bubbles on heating and could affect the bond quality. It is

important, therefore, that containers are kept closed and

sealed when not in use.

Cleaning:

Carbonised and set (non thermoplastic) material must be

removed mechanically. Removal of the thermoplastic

material from the hot apparatus can be achieved with

solvent free cleaning system, such as Macromelt 0062

(see separate technical information)

Safety Regulations

Storage:

When properly stored in a cool, dry location, with the

container tightly closed when not in use, this product will
